Unit 4 Forces ~newton's laws of motion

Front

What are field forces?

Back

Field forces are forces that act at a distance without direct contact, such as gravitational, electromagnetic, and nuclear forces.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What is frictional force?

Back

Frictional force is the force that opposes the motion of an object when it is in contact with another surface.

Front

What is tension force?

Back

Tension force is the force exerted by a rope, string, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is spring force?

Back

Spring force is the force exerted by a compressed or stretched spring, which follows Hooke's Law (F = -kx).

Front

How does friction affect a moving object?

Back

Friction can cause a moving object to slow down, stop, or move at a constant speed depending on the balance of forces.

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion; it is directly related to the object's mass.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

In Newton's 2nd Law, an increase in mass results in a decrease in acceleration if the net force remains constant.
